Adsorption of solid particles to a fluid/fluid interface can
reduce the total interfacial energy of a system of three fluid
bulk phases in such a way that the particles induce the wetting
of a fluid/fluid interface by a liquid, which does not wet this
interface in the absence of particles. This particle-assisted
wetting is most prominent if the contact angles at the
fluid/fluid/particle contact lines are close to 
and if the
spreading coefficient of the wetting liquid is negative but close
to zero.
